A: he most common use of the term "predisposing factors" in the field of public health has been in the context of L. W. Green's PRECEDE-PROCEED model of community health promotion planning and evaluation. [ Years of research have shown that literally hundreds of factors have the potential to influence a given health-related behaviorither by encouraging the behavior to occur or by inhibiting it from

occurring. Green's original PRECEDE model of health education planning and evaluation and the more recent PRECEDE-PROCEED model group these factors into three types: predisposing, reinforcing, and enabling factors. "Predisposing factors" are defined in these models as factors that exert their effects prior to a behavior occurring, by increasing or decreasing a person or population's motivation to undertake that particular behavior ]
